Cruz, being born in Canada, was a citizen at birth. Eleanor appears on voter a carefully multi-vetted voter registration list restricted to verified Canadian citizens. There is one condition that allows a person to nationalize in Canada in One Year. The condition could ***EASILY*** apply to Eleanor Cruz. Indeed, it is the ONLY realistic explanation for her name appearing on a list confined to Canadian citizens only.
Surely you know to what condition I refer.
Yes, a 1974 list and residence from 1967 is certain proof of her citizenship in 1970. Oh...wait...no it isn't.
